Title: Printing head of wire dot printer
Inventor: KITADE YUJIRO
IPC: B41J2/28
Filed: 1988-06-01
Abstract: PURPOSE:To enhance printing quality and to increase a printing speed by constituting the printing head of a wire dot printer by providing a shortcircuit ring which suppresses the leakage of the magnetic flux passing through a connection part, to the connection part. CONSTITUTION:When the leak magnetic flux passing through a connection part 22 is ready to increase, the shortcircuit current based on an increase in the leak magnetic flux is induced in a shortcircuit coil 28 to suppress the increase in the above mentioned leak magnetic flux. Therefore, the degree of magnetic interference is reduced after all and the control of magnetic flux in a closed magnetic path 18 is smoothly performed. As a result, since the printing operation of a printing wire 11 is performed certainly at a high speed in this printing head, the printing head imparting good printing quality and having a high printing speed is obtained.

Filed: 1990-05-23
Abstract: PURPOSE:To continue an operation between other normal equipments even when any one equipment generates a fault in an information system serially connecting the plural equipments by using optical fibers by remaining one part of input light as output light as it is. CONSTITUTION:An input light connector 21 splits the input into first and second polarized input beams and applies the 90% of the first polarized input beam, for example, to an information processing means 23 after reflecting it, inputting it to a photoelectric converting means 22 and converting the light to an electric signal. The information processing means 23 executes a required signal processing and applies the output to an output light connector as a polarized output beam after converting the output to an optical signal by an electrooptical converting means 24. The output light connector 25 forms the output light by synthesizing the polarized output beam and the second polarized input beam. Therefore, even when any one information processing means generates the fault in the information transmission system connecting the information processing means 23 in the shape of a loop, the second polarized input beam is outputted to the following information processing means as it is. Thus, even when one equipment generates the fault, the operation of the entire system can be guaranteed.
